Exanthems Respecting the Face

Diagnostic Approach

The American College of Dermatology suggests that exanthems respecting the face are primarily associated with specific etiologies, requiring systematic evaluation based on morphology, distribution, and temporal characteristics to guide appropriate management 1, 2

Erythema with pustules suggests drug reactions (especially EGFR or MEK inhibitors) or generalized acute pustular exanthem, according to the European Society of Clinical Microbiology and Infectious Diseases 1, 2

For papulopustular eruptions (e.g., EGFR/MEK inhibitors), the National Comprehensive Cancer Network recommends initiating oral tetracyclines (doxycycline 100 mg twice daily or minocycline 100 mg daily) for at least 6 weeks, and applying low-to-moderate potency topical corticosteroids (hydrocortisone 2.5% or alclometasone 0.05%) twice daily 1, 3
The use of humectants without alcohol, containing urea 5-10%, at least twice daily is also recommended by the American Academy of Dermatology 1, 3

If bacterial superinfection is suspected, the Infectious Diseases Society of America suggests obtaining bacterial cultures BEFORE initiating antibiotics, and administering appropriate antibiotics for at least 14 days 3, 4

The American Academy of Dermatology recommends avoiding frequent washing with hot water, irritants, over-the-counter acne medications, solvents, or disinfectants, and applying humectants without alcohol regularly to maintain the skin's barrier function 1, 3
Using sunscreen (SPF 15 or higher) on exposed areas, and gentle, non-irritating cleansers is also advised by the National Institute of Health 1, 3

The American Academy of Dermatology suggests referring urgently if exanthems are grade 3-4, or if there are systemic symptoms, suspicion of autoimmune skin disease, or no response to first-line treatment after 2 weeks 1, 2, 3
